a. 0.20
b. 0.00005
c. 0.41
d. 0.19
Number of ways to choose 5-card poker hand from a well-shuffled deck of 52 cards is,
= 2598960
Number of ways to choose one diamond from 13 diamonds in well-shuffled deck is 13.
Number of ways to choose remaining 4 cards from remaining 39 non-diamond card in well-shuffled deck is
= 82251
Probability that your hand will contain exactly one diamond = Number of ways to choose one diamond * Number of ways to choose remaining 4 cards / Number of ways to choose 5-card poker hand
= (82251 * 13) / 2598960
